Application filed June 26, 1906. Serial No. 323,464.

lathing or foundation upon which is imposed the interior plaster iinish of buildings, and has for its object to provide a simple and eflieient structural formation of a wood lathing-sheet capable of easy and economical production and .'which, while affording. an efiicient foundation for the plaster, requires but a minimum amount of the same in forming the necessary clenching-bond between 1 illustrated .drawings,

with the described the plaster and the lathing-sheet, all-as will herein after more fully appear. I

In the, accompanying drawings, illustrative of the present'invention, Figure 1 is an elevation of a portion of the wood lathing sheet. Fig. 2 is an edge View; of the same.

Referring to the drawings, 1 represents the main body of the lathing-sheet formed of a Wood vneeror sheet of the required thickness and which in the present improvement is formed with a series of com'parativel short cuts or slits 2, arranged in pairs, which have a parallel and separated relation to form a series of strips 3, integrally connected at. their respective ends to the main body 1,

as shown- The entire sheet r'body will be provided pairs of slits 2, and in the preferred form of the present invention, as more particularly in Fig. '1 of the the series of pairs of. slits 2 and strips 3 will have an alternated or staggered relation to each other, with their ends overlapping or extending past each other, as Shown. Preference is given to such construction, for the reason'that the natural shrinkage of the main body l is localized to many points and a checking and splitting of the same is avoided in a Very perfect manner. a

4 area series of transversely extending separator bars or strips which are inserted betweenthe aforesaid strips 3 andthe main body 1 while such parts are sprun'g apart to form sheds to receive the bars 4., and said bars are subsequently held by the natural elasticity of the strips 3. The bars 4 ma extend as single pieces the full width of the lathing-sheet or be made in a number of shorter sections having an end-to-endarrangement.

'With the described construction-lateral orifices are formed in the lathing-sheet for the passage of portionsof the walleplaster to attain a proper clenching of the same in place and with the naturaladherence of the plas-- ter to the wooden surface of the sheetaiiords a strong and durable attachment of the plaster in place. I

ln'actual use either side of the Sheet 1 may be used to plaster upon, it being preferred for a finer class of Work to plaster upon the side ol the sheet 1 opposite to that on Which the transverse separator-bars 4 are arranged.

.Ilaving thus fully described my said in: vention, what I claim as new, and desire to secure by Letters Patent, is-

1. A lathing for plastering, comprising a sheet of woodformed \yitha series in turn form integrals'trips, and transverse separator-bars arranged tween said strips and'the sheet.

2. A lathing for plastering, comprising a sheet of wood formed with a series of slits to in turn form integral strips, and transverse separator-bars of wood arranged in sheds formed between said strips and the sheet.

'3. A lathing for plastering, comprisin a Sheet of wood formed with a series of sits arranged in pairs having a st'ag ered relation and forming a series of strips having a like Staggered relation, and transverse separator are arranged in sheds formed between said strips and the sheet. 4
